Mixed Signal PCB Design STM Atmel ESP32 programming

Hi There, I am a senior Expert and Have more than 5 years of experience in electronics and embedded design. I have experience in STM mcu and familiar with SIM800 module as well and have this gsm in hand for proper testing as well. I also have experience in pcb desiging. Just check my profile and share your details. Time and Budget will be discussed. Thanks

HELLO; I am working as a research and development manager in a private company. I have more than 8 years of experience in embedded system software and hardware. As for software, I am proficient in microcontrollers such as (*****STM32*****), MICROCHIP, NUVOTON,ARDUINO,ESP32,MSP430,RASPBERRY Pİ. I have experience in communication protocols such as CanBus, ModBus, RS232, RS485,SPI,I2C, TCP IP, Socket Communication. I am an expert in Altium and KiCad programs in hardware. I have read and understood your project. Please write to me for details.

Good day I am a hardware and firmware developer with 5 years experience developing IoT and telemetric products. I have developed hardware and firmware for numerous vehicle and asset tracking products I have also developed a ESP32 based project to read 16 analog inputs via a multiplexer, I have recently designed and built a modem based on SIM800L and CH340T which I use as a SMS modem that receives SMSs and saves it in a DB, I can easily modify it to suit your needs. You may check my portfolio to view some of the PCB I have developed that are currently being produced. I believe that my experience would be of much use to complete your PCBs as required. Feel free to message me to discuss your project, budget and timeline in more detail

hello. as an experienced electrical engineer I am confident i can be able to produce the design of the specified pcb in the required time period. I have worked with atmega, NXP among other microcontrollers in my previous jobs and would be proud to work with you

I'm Piyush, an experienced and multifaceted embedded systems engineer with a solid emphasis on PCB design. Over the past two years, I've cultivated my skills in developing STM32, Atmega, NXP, and ESP32 embedded systems as per your project requirements. I've successfully completed similar projects like yours and have the knowledge and hands-on experience to read SMS from SIM800L with ESP32, searching for passwords, and sending emails via Wi-Fi. Assembling and testing software on hardware is my forte; your project is precisely aligned with what I do best. Utilizing platforms like Visual Studio Code and languages including C/assembler for communication with GSM modules and Python for email functions, I am confident in delivering effective solutions tailored to your needs. Beyond being a proficient software developer, I also possess ample experience using popular PCB layout tools such as Altium and Orcad. In fact, on one of my recent projects, I leveraged my PCB design skills to adapt two crucial industrial protocols using a Raspberry Pi 4. This reflects my commitment to not only writing impeccable code but also ensuring that it performs optimally on the hardware. Choosing my expertise means opting for reliable solutions and earning a preferred contact for your future projects

With over 5 years of experience in Hardware and Embedded Systems design, I believe that I can provide the expertise you need for your project. My knowledge stretches across a wide range of microcontrollers including STM32, Atmega, NXP, and ESP32. This includes not only software development but also PCB design and assembly. In fact, I have successfully built several mixed signal PCBs in the past, one of which utilized both LAN and 485 ports, similar to the project you had completed two years ago with Ariel and Alan. Additionally, my proficiency in C/Assembler programming makes me highly capable in handling the communication between the GSM module (SIM800L) and the ESP32, which is crucial for your project requirements. Moreover, as an experienced hardware designer, I am well-versed in designing compact PCB layouts adhering to both your specifications as well as industrial compliance standards. By choosing me for this project, you'll not only get someone who can deliver on your current SMS-ESP32 task but also a potential long-term collaborator for all your future projects on Freelancer. So, let's partner up and make great things together!
